PhysicsQ&A LibraryA 12-kg block on a horizontal frictionless surface is attached to a light spring (force constant 0.80 kN/m). The block is initially at rest at its equilibrium position when a force (magnitude P- 80 N) acting parallel to the surface is applied to the block, as shown. What is the speed of the block when it is 13 cm from its equilibrium position? a. 0.78 m/s b. 0.81 m/s c. 0.71 m/s d. 0.58 m/s e. 0.64 m/sQuestion
